Almost a perfect replacement
September 05, 2022

I was replacing the original Motor Controller board (uncontrollable speed). The installation instructions were easy to follow. I suggest you get some small cable zip ties before you start. I had to clip a few cable ties to allow cable movement & used cable zip ties to rebundle the wires when finished. Calibrating the speed instructions didn't seem to work well. I could not get the speed between 9.7 & 10.3 mph using the speed potentiometer. Oh well, I don't walk that fast anyway. It seemed to be fine at 3 to 4 mph. I'll try the Owner's Manual (Pro Form CX 18i) calibration instructions next. It seems slightly different.

Easy to install
November 21, 2021

Tried to do calibration per instructions but my display mph did not show anything. The phillips screw to adjust is basically flat such that even a control size driver did not turn it easily. My mph does seem to work but blanks after a short time and displays correctly each time the speed changes. I am guessing it could now be my circuit board under the display.
